Sustained Transmission of Neisseria gonorrhoeae with High-Level Resistance to Azithromycin, in Indianapolis, Indiana, 2017-2018.

BACKGROUND: Since 2014, Neisseria gonorrhoeae azithromycin (AZM) susceptibility has declined in the United States, but high-level AZM resistance (HL-AZMR) has been infrequent and sporadic. We describe a cluster of 14 N. gonorrhoeae isolates with HL-AZMR identified in Indianapolis over 13 months. METHODS: N. gonorrhoeae culture specimens (genital and extragenital) were collected from attendees of the Bell Flower Clinic. Isolates underwent antimicrobial susceptibility testing (AST) using Etest. AZM minimum inhibitory concentrations ≥256 µg/mL were classified as HL-AZMR. Local disease intervention specialists interviewed patients whose isolates demonstrated HL-AZMR and conducted partner services. Relatedness of isolates was investigated by genomic analyses. RESULTS: During 2017-2018, AST was performed in 1016 N. gonorrhoeae isolates collected at the Bell Flower Clinic. Fourteen isolates (1.4%) from 12 men collected over 13 months demonstrated HL-AZMR; all were cephalosporin susceptible. Of the 12 men, 9 were white and reported male sex partners. Nine of the men were able to be retested; all were cured with 250-mg ceftriaxone plus 1-g AZM. Two men named each other as partners; no other partners in common were reported. Genomic analysis demonstrated close relatedness of the HL-AZMR isolates and a novel combination of a mosaic-mtrR promoter along with 23S ribosomal RNA mutations that appear to have emerged from circulating strains. CONCLUSIONS: The close genetic relatedness with limited epidemiologic linkages between patients highlights the challenges of gonorrhea partner investigations and suggests undetected local transmission. Local AST, rapid public health action, and epidemiologic investigations combined with genomic analysis provides a multipronged approach to understanding an outbreak of sexually transmitted disease.

Strengthening the US Response to Resistant Gonorrhea: An Overview of a Multisite Program to Enhance Local Response Capacity for Antibiotic-Resistant Neisseria gonorrhoeae.

BACKGROUND: In 2016, Centers for Disease Control and Prevention initiated Strengthening the US Response to Resistant Gonorrhea (SURRG) in multiple jurisdictions to enhance antibiotic resistant gonorrhea rapid detection and response infrastructure and evaluate the impact of key strategies. METHODS: Eight jurisdictions were funded to establish or enhance local gonococcal culture specimen collection in sexually transmitted disease and community clinics, conduct rapid antimicrobial susceptibility testing (AST) in local laboratories, modify systems for enhanced data collection and rapid communication of results, and initiate enhanced partner services among patients with gonorrhea demonstrating elevated minimum inhibitory concentrations (MICs) to ceftriaxone, cefixime or azithromycin. RESULTS: Grantees incorporated genital, pharyngeal, and rectal gonococcal culture collection from all genders at participating clinics. During 2018 to 2019, grantees collected 58,441 culture specimens from 46,822 patients and performed AST on 10,814 isolates (representing 6.8% [3412] and 8.9% [4883] of local reported cases in 2018 and 2019, respectively). Of isolates that underwent AST, 11% demonstrated elevated azithromycin MICs; fewer than 0.5% demonstrated elevated ceftriaxone or cefixime MICs. Among patients whose infections demonstrated elevated MICs, 81.7% were interviewed for partner elicitation; however, limited new cases were identified among partners and contacts. CONCLUSIONS: As a public health model to build capacity to slow the spread of emerging resistance, SURRG successfully expanded culture collection, implemented rapid AST, and implemented an enhanced partner services investigation approach in participating jurisdictions. Findings from SURRG may enhance preparedness efforts and inform a longer-term, comprehensive, and evidence-based public health response to emerging gonococcal resistance. Continued development of innovative approaches to address emerging resistance is needed.

Exploring and Comparing the Structure of Sexual Networks Affected by Neisseria gonorrhoeae Using Sexual Partner Services Investigation and Genomic Data.

BACKGROUND: Sexual networks are difficult to construct because of incomplete sexual partner data. The proximity of people within a network may be inferred from genetically similar infections. We explored genomic data combined with partner services investigation (PSI) data to extend our understanding of sexual networks affected by Neisseria gonorrhoeae (NG). METHODS: We used 2017-2019 PSI and whole-genome sequencing (WGS) data from 8 jurisdictions participating in Centers for Disease Control and Prevention's Strengthening the US Response to Resistant Gonorrhea (SURRG) project. Clusters were identified from sexual contacts and through genetically similar NG isolates. Sexual mixing patterns were characterized by describing the clusters by the individual's gender and gender of their sex partners. RESULTS: Our study included 4627 diagnoses of NG infection (81% sequenced), 2455 people received a PSI, 393 people were negative contacts of cases, and 495 were contacts with an unknown NG status. We identified 823 distinct clusters using PSI data combined with WGS data. Of cases that were not linked to any other case using PSI data, 37% were linked when using WGS data. Overall, 40% of PSI cases were allocated to a larger cluster when PSI and WGS data were combined compared with PSI data alone. Mixed clusters containing women, men who report sex with women, and men who report sex with men were common when using the WGS data either alone or in combination with the PSI data. CONCLUSIONS: Combining PSI and WGS data improves our understanding of sexual network connectivity.

A community-driven resource for genomic epidemiology and antimicrobial resistance prediction of Neisseria gonorrhoeae at Pathogenwatch.

BACKGROUND: Antimicrobial-resistant (AMR) Neisseria gonorrhoeae is an urgent threat to public health, as strains resistant to at least one of the two last-line antibiotics used in empiric therapy of gonorrhoea, ceftriaxone and azithromycin, have spread internationally. Whole genome sequencing (WGS) data can be used to identify new AMR clones and transmission networks and inform the development of point-of-care tests for antimicrobial susceptibility, novel antimicrobials and vaccines. Community-driven tools that provide an easy access to and analysis of genomic and epidemiological data is the way forward for public health surveillance. METHODS: Here we present a public health-focussed scheme for genomic epidemiology of N. gonorrhoeae at Pathogenwatch ( https://pathogen.watch/ngonorrhoeae ). An international advisory group of experts in epidemiology, public health, genetics and genomics of N. gonorrhoeae was convened to inform on the utility of current and future analytics in the platform. We implement backwards compatibility with MLST, NG-MAST and NG-STAR typing schemes as well as an exhaustive library of genetic AMR determinants linked to a genotypic prediction of resistance to eight antibiotics. A collection of over 12,000 N. gonorrhoeae genome sequences from public archives has been quality-checked, assembled and made public together with available metadata for contextualization. RESULTS: AMR prediction from genome data revealed specificity values over 99% for azithromycin, ciprofloxacin and ceftriaxone and sensitivity values around 99% for benzylpenicillin and tetracycline. A case study using the Pathogenwatch collection of N. gonorrhoeae public genomes showed the global expansion of an azithromycin-resistant lineage carrying a mosaic mtr over at least the last 10 years, emphasising the power of Pathogenwatch to explore and evaluate genomic epidemiology questions of public health concern. CONCLUSIONS: The N. gonorrhoeae scheme in Pathogenwatch provides customised bioinformatic pipelines guided by expert opinion that can be adapted to public health agencies and departments with little expertise in bioinformatics and lower-resourced settings with internet connection but limited computational infrastructure. The advisory group will assess and identify ongoing public health needs in the field of gonorrhoea, particularly regarding gonococcal AMR, in order to further enhance utility with modified or new analytic methods.

Sexually Transmitted Infection Testing Among Transgender Women Living with Human Immunodeficiency Virus in the United States: Medical Monitoring Project, 2015-2019.

National guidelines recommend annual sexually transmitted infection testing for sexually active people living with human immunodeficiency virus, including transgender women. Using data from the US Medical Monitoring Project during 2015-2019, in the previous 12 months, 63.3% of sexually active transgender women who were human immunodeficiency virus positive were tested for syphilis, 56.6% for chlamydia, and 54.4% for gonorrhea.

Genomic and Phenotypic Variability in Neisseria gonorrhoeae Antimicrobial Susceptibility, England.

Antimicrobial resistance (AMR) in Neisseria gonorrhoeae is a global concern. Phylogenetic analyses resolve uncertainties regarding genetic relatedness of isolates with identical phenotypes and inform whether AMR is due to new mutations and clonal expansion or separate introductions by importation. We sequenced 1,277 isolates with associated epidemiologic and antimicrobial susceptibility data collected during 2013-2016 to investigate N. gonorrhoeae genomic variability in England. Comparing genetic markers and phenotypes for AMR, we identified 2 N. gonorrhoeae lineages with different antimicrobial susceptibility profiles and 3 clusters with elevated MICs for ceftriaxone, varying mutations in the penA allele, and different epidemiologic characteristics. Our results indicate N. gonorrhoeae with reduced antimicrobial susceptibility emerged independently and multiple times in different sexual networks in England, through new mutation or recombination events and by importation. Monitoring and control for AMR in N. gonorrhoeae should cover the entire population affected, rather than focusing on specific risk groups or locations.

Phylogenomic analysis of Neisseria gonorrhoeae transmission to assess sexual mixing and HIV transmission risk in England: a cross-sectional, observational, whole-genome sequencing study.

BACKGROUND: Characterising sexual networks with transmission of sexually transmitted infections might allow identification of individuals at increased risk of infection. We aimed to investigate sexual mixing in Neisseria gonorrhoeae transmission networks between women, heterosexual men, and men who report sex with men (MSM), and between people with and without HIV. METHODS: In this cross-sectional observational study, we whole-genome sequenced N gonorrhoeae isolates from the archive of the Gonococcal Resistance to Antimicrobials Surveillance Programme (GRASP).w Isolates that varied by five single nucleotide polymorphisms or fewer were grouped into clusters that represented sexual networks with N gonorrhoeae transmission. Clusters were described by gender, sexual risk group, and HIV status. FINDINGS: We sequenced 1277 N gonorrhoeae isolates with linked clinical and sociodemographic data that were collected in five clinics in England during 2013-16 (July 1 to Sept 30 in 2013-15; July 1 to Sept 9 in 2016). The isolates grouped into 213 clusters. 30 (14%) clusters contained isolates from heterosexual men and MSM but no women and three (1%) clusters contained isolates from only women and MSM. 146 (69%) clusters comprised solely people with negative or unknown HIV status and seven (3%) comprised only HIV-positive people. 60 (28%) clusters comprised MSM with positive and negative or unknown HIV status. INTERPRETATION: N gonorrhoeae molecular data can provide information indicating risk of HIV or other sexually transmitted infections for some individuals for whom such risk might not be known from clinical history. These findings have implications for sexual health care, including offering testing, prevention advice, and preventive treatment, such as HIV pre-exposure prophylaxis.

Just Google it! Impact of media coverage of an outbreak of high-level azithromycin-resistant Neisseria gonorrhoeae on online searches, and attendances, testing and diagnoses at sexual health clinics in England between 2015 and 2016: an interrupted time series analysis using surveillance data.

OBJECTIVES: To determine if media coverage of an outbreak of high-level azithromycin-resistant Neisseria gonorrhoeae (HL-AziR) impacted online search interest or was temporally associated with health-seeking behaviours in several English cities. METHODS: A descriptive analysis of outbreak-related online media articles and relative search interest (RSI) using Google and an interrupted time series analysis using routine surveillance data from sexual health clinics (SHCs) in England (GUMCAD STI surveillance system). The main outcomes were adjusted incidence rate ratios (IRRs) of weekly attendances, gonorrhoea tests and diagnoses of gonorrhoea or 'any STI' in selected cities after media coverage of the outbreak in 2015 and 2016. RESULTS: RSI for outbreak-related terms peaked during media coverage in September 2015 with smaller peaks coinciding with subsequent coverage. The greatest increase in RSI was in Leeds, which coincided with a 63% rise (n=1932; IRR 1.26, 95% CI 1.12 to 1.43) in SHC attendances by women. There was only a 7% (n=1358; IRR 1.01, 95% CI 0.91 to 1.11) increase in attendances by men. Modest increases in outcomes occurred in four other cities with a high RSI. There was no evidence of increases in outcomes in cities, other than Leeds, after subsequent media coverage of the outbreak. CONCLUSIONS: National and local media coverage of the HL-AziR outbreak coincided with peak RSI for related terms, and a transient increase in attendances, gonorrhoea tests and diagnoses of gonorrhoea or 'any STI' in some cities with a high RSI. Our analysis demonstrates the potential for media coverage to influence health-seeking behaviours during high-profile STI outbreaks.

Detection in the United Kingdom of the Neisseria gonorrhoeae FC428 clone, with ceftriaxone resistance and intermediate resistance to azithromycin, October to December 2018.

We describe detection in the United Kingdom (UK) of the drug-resistant Neisseria gonorrhoeae FC428 clone, with ceftriaxone resistance and intermediate azithromycin resistance. Two female patients developed infection following contact with UK-resident men from the same sexual network linked to travel to Ibiza, Spain. One case failed treatment with ceftriaxone, and azithromycin and gentamicin, before successful treatment with ertapenem. Both isolates had indistinguishable whole-genome sequences. Urgent action is essential to contain this drug-resistant strain.

Qualitative impact assessment of an educational workshop on primary care practitioner attitudes to NICE HIV testing guidelines.

BACKGROUND: In 2013, Public Health England piloted the '3Cs (chlamydia, contraception, condoms) and HIV (human immunodeficiency virus)' educational intervention in 460 GP surgeries. The educational HIV workshop aimed to improve the ability and confidence of staff to offer HIV testing in line with national guidelines. AIM: To qualitatively assess the impact of an educational workshop on GP staff's attitudes to NICE HIV testing guidelines. DESIGN & SETTING: Qualitative interviews with GP staff across England before and after an educational HIV workshop. METHOD: Thirty-two GP staff (15 before and 17 after educational HIV workshop) participated in interviews exploring their views and current practice of HIV testing. Interview transcripts were thematically analysed and examined, using the components of the theory of planned behaviour (TPB) and normalisation process theory (NPT) as a framework. RESULTS: GPs reported that the educational HIV workshop resulted in increased knowledge of, and confidence to offer, HIV tests based on indicator conditions. However, overall participants felt they needed additional HIV training around clinical care pathways for offering tests, giving positive HIV results, and current treatments and outcomes. Participants did not see a place for point-of-care testing in general practice. CONCLUSION: Implementation of national HIV guidelines will require multiple educational sessions, especially to implement testing guidelines for indicator conditions in areas of low HIV prevalence. Additional role-play or discussions around scripts suggesting how to offer an HIV test may improve participants' confidence and facilitate increased testing. Healthcare assistants (HCAs) may need specific training to ensure that they are skilled in offering HIV testing within new patient checks.

Neisseria gonorrhoeae molecular typing for understanding sexual networks and antimicrobial resistance transmission: A systematic review.

OBJECTIVES: Neisseria gonorrhoeae (NG) is a significant global public health concern due to rising diagnoses rates and antimicrobial resistance. Molecular combined with epidemiological data have been used to understand the distribution and spread of NG, as well as relationships between cases in sexual networks, but the public health value gained from these studies is unclear. We conducted a systematic review to examine how molecular epidemiological studies have informed understanding of sexual networks and NG transmission, and subsequent public health interventions. METHODS: Five research databases were systematically searched up to 31st March 2017 for studies that used sequence-based DNA typing methods, including whole genome sequencing, and linked molecular data to patient-level epidemiological data. Data were extracted and summarised to identify common themes. RESULTS: Of the 49 studies included, 82% used NG Multi-antigen Sequence Typing. Gender and sexual orientation were commonly used to characterise sexual networks that were inferred using molecular clusters; clusters predominantly of one patient group often contained a small number of isolates from other patient groups. Suggested public health applications included using these data to target interventions at specific populations, confirm outbreaks, and inform partner management, but these were mainly untested. CONCLUSIONS: Combining molecular and epidemiological data has provided insight into sexual mixing patterns, and dissemination of NG, but few studies have applied these findings to design or evaluate public health interventions. Future studies should focus on the application of molecular epidemiology in public health practice to provide evidence for how to prevent and control NG.

Is previous azithromycin treatment associated with azithromycin resistance in Neisseria gonorrhoeae? A cross-sectional study using national surveillance data in England.

OBJECTIVES: It has been suggested that treatment of STIs with azithromycin may facilitate development of azithromycin resistance in Neisseria gonorrhoeae (NG) by exposing the organism to suboptimal doses. We investigated whether treatment history for non-rectal Chlamydia trachomatis (CT), non-gonococcal urethritis (NGU) or NG (proxies for azithromycin exposure) in sexual health (GUM) services was associated with susceptibility of NG to azithromycin. METHODS: Azithromycin susceptibility data from the Gonococcal Resistance to Antimicrobials Surveillance Programme (GRASP 2013-2015, n=4606) and additional high-level azithromycin-resistant isolates (HL-AziR) identified by the Public Health England reference laboratory (2013-2016, n=54) were matched to electronic patient records in the national GUMCAD STI surveillance dataset (2012-2016). Descriptive and regression analyses were conducted to examine associations between history of previous CT/NGU/NG and subsequent susceptibility of NG to azithromycin. RESULTS: Modal azithromycin minimum inhibitory concentration (MIC) was 0.25 mg/L (one dilution below the resistance breakpoint) in those with and without history of previous CT/NGU/NG (previous 1 month/6 months). There were no differences in MIC distribution by history of CT/NGU (P=0.98) or NG (P=0.85) in the previous 1 month/6 months or in the odds of having an elevated azithromycin MIC (>0.25 mg/L) (Adjusted OR for CT/NGU 0.97 (95% CI 0.76 to 1.25); adjusted OR for NG 0.82 (95% CI: 0.65 to 1.04)) compared with those with no CT/NGU/NG in the previous 6 months. Among patients with HL-AziR NG, 3 (4%) were treated for CT/NGU and 2 (3%) for NG in the previous 6 months, compared with 6% and 8%, respectively for all GRASP patients. CONCLUSIONS: We found no evidence of an association between previous treatment for CT/NGU or NG in GUM services and subsequent presentation with an azithromycin-resistant strain. As many CT diagnoses occur in non-GUM settings, further research is needed to determine whether azithromycin-resistant NG is associated with azithromycin exposure in other settings and for other conditions.

Linkage to HIV care following diagnosis in the WHO European Region: A systematic review and meta-analysis, 2006-2017.

BACKGROUND: Timely linkage to care after HIV diagnosis is crucial as delayed access can result in poor patient outcomes. The aim of this systematic review was to synthesise the evidence to achieve a better understanding of what proportion of patients are linked to care and what factors impact linkage. METHODS: Systematic searches were run in six databases up to the end of February 2017. The grey literature was also reviewed. Inclusion criteria were: sample size ≥50 people (aged ≥15), from the WHO European Region, published 2006-2017 and in English. Linkage to care was defined as a patient seen for HIV care after diagnosis. Study selection, data extraction and quality assurance were performed by two independent reviewers. Random-effects meta-analysis was carried out to summarise linkage to care within three months of diagnosis. RESULTS: Twenty-four studies were included; 22 presented linkage to care data and seven examined factors for linkage. Linkage among 89,006 people in 19 countries was captured. Meta-analysis, restricted to 12 studies and measuring prompt linkage within three months, gave a pooled estimate of 85% (95% CI: 75%-93%). Prompt linkage was higher in studies including only people in care (94%; 95% CI: 91%-97%) than in those of all new diagnoses (71%; 95% CI: 50%-87%). Heterogeneity was high across and within strata (>99%). Factors associated with delaying or not linking to care included: acquiring HIV through heterosexual contact/injecting drug use, younger age at diagnosis, lower levels of education, feeling well at diagnosis and diagnosis outside an STI clinic. CONCLUSION: Overall, linkage to care was high, though estimates were lower in studies with a high proportion of people who inject drugs. The high heterogeneity between studies made it challenging to synthesise findings. Studies should adopt a standardised definition with a three month cut-off to measure prompt linkage to care to ensure comparability.

Detection of Chlamydia trachomatis in rectal specimens in women and its association with anal intercourse: a systematic review and meta-analysis.

OBJECTIVES: Chlamydia trachomatis is the most commonly diagnosed bacterial STI. Lack of prevalence and risk factor data for rectal chlamydia in women has testing and treatment implications, as azithromycin (a first-line urogenital chlamydia treatment) may be less effective for rectal chlamydia. We conducted a systematic review of studies on women in high-income countries to estimate rectal chlamydia prevalence, concurrency with urogenital chlamydia and associations with reported anal intercourse (AI). DESIGN: Systematic review and four meta-analyses conducted using random-effects modelling. DATA SOURCES: Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, PsycINFO and the Cochrane Database were searched for articles published between January 1997 and October 2017. ELIGIBILITY CRITERIA: Studies reporting rectal chlamydia positivity in heterosexual women aged ≥15 years old in high-income countries were included. Studies must have used nucleic acid amplification tests and reported both the total number of women tested for rectal chlamydia and the number of rectal chlamydia infections detected. Conference abstracts, case reports and studies with self-reported diagnoses were excluded. Data extracted included setting, rectal and urogenital chlamydia testing results, AI history, and demographics. RESULTS: Fourteen eligible studies were identified, all among diverse populations attending sexual health services. Among routine clinic-attending women, summary rectal chlamydia positivity was 6.0% (95% CI 3.2% to 8.9%); summary concurrent rectal chlamydia infection was 68.1% in those who tested positive for urogenital chlamydia (95% CI 56.6% to 79.6%); and of those who tested negative for urogenital chlamydia, 2.2% (95% CI 0% to 5.2%) were positive for rectal chlamydia. Reported AI was not associated with rectal chlamydia (summary risk ratio 0.90; 95% CI 0.75 to 1.10). CONCLUSIONS: High levels of rectal chlamydia infection have been shown in women with urogenital chlamydia infection. The absence of association between reported AI and rectal chlamydia suggests AI is not an adequate indicator for rectal testing. Further work is needed to determine policy and practice for routine rectal testing in women.

Prevalence of and factors associated with MDR Neisseria gonorrhoeae in England and Wales between 2004 and 2015: analysis of annual cross-sectional surveillance surveys.

Objectives: To describe trends in prevalence, susceptibility profile and risk factors for MDR Neisseria gonorrhoeae (MDR-NG) in England and Wales. Methods: Isolates from 16 242 gonorrhoea episodes at sexual health clinics within the Gonococcal Resistance to Antimicrobials Surveillance Programme (GRASP) underwent antimicrobial susceptibility testing. MDR-NG was defined as resistance to ceftriaxone, cefixime or azithromycin, plus at least two of penicillin, ciprofloxacin and spectinomycin. Trends in resistance are presented for 2004-15; prevalence and logistic regression analyses for MDR-NG cover the period of the most recent treatment guideline (ceftriaxone plus azithromycin), 2011-15. Results: Between 2004 and 2015, the proportion of N. gonorrhoeae isolates fully susceptible to all antimicrobial classes fell from 80% to 46%, with the proportion resistant to multiple (two or more) classes increasing from 7.3% to 17.5%. In 2011-15, 3.5% of isolates were MDR-NG, most of which were resistant to cefixime (100% in 2011, decreasing to 36.9% in 2015) and/or azithromycin (4.2% in 2011, increasing to 84.3% in 2015). After excluding azithromycin-resistant isolates, modal azithromycin MICs were higher in MDR versus non-MDR isolates (0.5 versus 0.125 mg/L), with similar results for ceftriaxone (modal MICs 0.03 versus ≤0.002 mg/L). After adjustment for confounders, MDR-NG was more common among isolates from heterosexual men, although absolute differences in prevalence were small [4.6% versus 3.3% (MSM) and 2.5% (women)]. Conclusions: N. gonorrhoeae is becoming less susceptible to available antimicrobials. Since 2011, a minority of isolates were MDR-NG; however, MICs of azithromycin or ceftriaxone (first-line therapies) for many of these were elevated. These findings highlight the importance of continued antimicrobial stewardship for gonorrhoea.

Qualitative interviews with healthcare staff in four European countries to inform adaptation of an intervention to increase chlamydia testing.

OBJECTIVE: To determine the needs of primary healthcare general practice (GP) staff, stakeholders and trainers to inform the adaptation of a locally successful complex intervention (Chlamydia Intervention Randomised Trial (CIRT)) aimed at increasing chlamydia testing within primary healthcare within South West England to three EU countries (Estonia, France and Sweden) and throughout England. DESIGN: Qualitative interviews. SETTING: European primary healthcare in England, France, Sweden and Estonia with a range of chlamydia screening provision in 2013. PARTICIPANTS: 45 GP staff, 13 trainers and 18 stakeholders. INTERVIEWS: The iterative interview schedule explored participants' personal attitudes, subjective norms and perceived behavioural controls around provision of chlamydia testing, sexual health services and training in general practice. Researchers used a common thematic analysis. RESULTS: Findings were similar across all countries. Most participants agreed that chlamydia testing and sexual health services should be offered in general practice. There was no culture of GP staff routinely offering opportunistic chlamydia testing or sexual health advice, and due to other priorities, participants reported this would be challenging. All participants indicated that the CIRT workshop covering chlamydia testing and sexual health would be useful if practice based, included all practice staff and action planning, and was adequately resourced. Participants suggested minor adaptations to CIRT to suit their country's health services. CONCLUSIONS: A common complex intervention can be adapted for use across Europe, despite varied sexual health provision. The intervention (ChlamydiA Testing Training in Europe (CATTE)) should comprise: a staff workshop covering sexual health and chlamydia testing rates and procedures, action planning and patient materials and staff reminders via computer prompts, emails or newsletters, with testing feedback through practice champions. CATTE materials are available at: www.STItraining.eu.

Chlamydia and HIV testing, contraception advice, and free condoms offered in general practice: a qualitative interview study of young adults' perceptions of this initiative.

BACKGROUND: Opportunistic chlamydia screening is actively encouraged in English general practices. Based on recent policy changes, Public Health England piloted 3Cs and HIV in 2013-2014, integrating the offer of chlamydia testing with providing condoms, contraceptive information, and HIV testing (referred to as 3Cs and HIV) according to national guidelines. AIM: To determine young adults' opinions of receiving a broader sexual health offer of 3Cs and HIV at their GP practice. DESIGN AND SETTING: Qualitative interviews were conducted in a general practice setting in England between March and June 2013. METHOD: Thirty interviews were conducted with nine male and 21 female patients aged 16-24 years, immediately before or after a routine practice attendance. Data were transcribed verbatim and analysed using a thematic framework. RESULTS: Participants indicated that the method of testing, timing, and the way the staff member approached the topic were important aspects to patients being offered 3Cs and HIV. Participants displayed a clear preference for 3Cs and HIV to be offered at the GP practice over other sexual health service providers. Participants highlighted convenience of the practice, assurance of confidentiality, and that the sexual health discussion was appropriate and routine. Barriers identified for patients were embarrassment, unease, lack of time, religion, and patients believing that certain patients could take offence. Suggested facilitators include raising awareness, reassuring confidentiality, and ensuring the offer is made in a professional and non-judgemental way at the end of the consultation. CONCLUSION: General practice staff should facilitate patients' preferences by ensuring that 3Cs and HIV testing services are made available at their surgery and offered to appropriate patients in a non-judgemental way.

Service evaluation of an educational intervention to improve sexual health services in primary care implemented using a step-wedge design: analysis of chlamydia testing and diagnosis rate changes.

BACKGROUND: Providing sexual health services in primary care is an essential step towards universal provision. However they are not offered consistently. We conducted a national pilot of an educational intervention to improve staff's skills and confidence to increase chlamydia testing rates and provide condoms with contraceptive information plus HIV testing according to national guidelines, known as 3Cs&HIV. The effectiveness of the pilot on chlamydia testing and diagnosis rates in general practice was evaluated. METHODS: The pilot was implemented using a step-wedge design over three phases during 2013 and 2014 in England. The intervention combined educational workshops with posters, testing performance feedback and continuous support. Chlamydia testing and diagnosis rates in participating general practices during the control and intervention periods were compared adjusting for seasonal trends in chlamydia testing and differences in practice size. Intervention effect modification was assessed for the following general practice characteristics: chlamydia testing rate compared to national median, number of general practice staff employed, payment for chlamydia screening, practice urban/rurality classification, and proximity to sexual health clinics. RESULTS: The 460 participating practices conducted 26,021 tests in the control period and 18,797 tests during the intervention period. Intention-to-treat analysis showed no change in the unadjusted median tests and diagnoses per month per practice after receiving training: 2.7 vs 2.7; 0.1 vs 0.1. Multivariable negative binomial regression analysis found no significant change in overall testing or diagnoses post-intervention (incidence rate ratio (IRR) 1.01, 95 % confidence interval (CI) 0.96-1.07, P = 0.72; 0.98 CI 0.84-1.15, P = 0.84, respectively). Stratified analysis showed testing increased significantly in practices where payments were in place prior to the intervention (IRR 2.12 CI 1.41-3.18, P < 0.001) and in practices with 6-15 staff (6-10 GPs IRR 1.35 (1.07-1.71), P = 0.012; 11-15 GPs IRR 1.37 (1.09-1.73), P = 0.007). CONCLUSION: This national pilot of short educational training sessions found no overall effect on chlamydia testing in primary care. However, in certain sub-groups chlamydia testing rates increased due to the intervention. This demonstrates the importance of piloting and evaluating any service improvement intervention to assess the impact before widespread implementation, and the need for detailed understanding of local services in order to select effective interventions.
